Ambi Encoder Cryosphere

s3g Ambi Encoder Cryosphere is the frozen counterpart to Pyrosphere: a zero-input geological instrument in which frost and moving ice act on bedrock, substrate, snowpack, and water. Ice growth, strain, fracture, basal slip, calving, impact, cavitation, and granular transport are distributed across as many as 64 moving ACN/SN3D field voices.

Workflow

1. Insert s3g Ambi Encoder Cryosphere on a correctly routed 64-channel Ambisonic track, load a factory scene, and select the output ORDER.
2. Follow it with an ambisonic decoder.
3. Start the REAPER transport and listen to the scene's initial material and activity.
4. Choose an ice process and substrate, then shape its activity with the event, material, and score controls or move among stored states on the SURF page.

Cryogeology Model

The source is aperiodic. Each field voice accumulates frost, fracture, and basal-slip stress. Surface ice divides this behavior across slab flex, fault lines, and fine cracks; granular transport scrapes the selected substrate. Calving separates detachment from its later water impact and cavitation tail. Short body responses provide scale without a persistent resonator bed.

The ice and fracture controls shape event rate, branching, mass, brightness, and decay. EVENT RATE is the master clock from HOLD to 1×. Scale, depth, substrate, and fracture mass move the response from crisp surface cracks to broad plate and sub-ice pressure. Separate controls add footsteps, plate failure, granules, frozen impacts, calving, and brine activity.

SINGING LAKE briefly applies each crack’s stochastic force to a scattered inharmonic modal pair. Scale and depth place the response; brightness, snap, scatter, and damping shape it. The modes sound only during events rather than forming a continuous ringing bed.

The four planetary regimes use distinct processes: APERIODIC LATTICE propagates defect fronts through non-repeating frozen matter; TIDAL SHELL releases stress between an ocean and frozen crust; HYDROCARBON DUNE combines frost shear, avalanches, and microfracture; and REACTIVE BRINE cycles pore pressure through sealing and blow-through. Their events briefly excite distributed mineral modes.

The fracture, ice-segregation, basal-slip, and iceberg-impact paths are informed by geophysics, but this is a realtime procedural interpretation—not a predictive glacier model. See References.

Aleatoric entity score

Each field voice is a finite plate, substrate region, brine pocket, or ice mass. The score moves it through stillness, loading, fracture, propagation, rupture or displacement, and settling. Cracks travel to nearby plates; calving schedules a delayed impact; Ice Under Foot advances a load across successive plates.

PACE sets event turnover, OCCUPANCY sets the loaded population, CASCADE controls propagation, MEMORY carries patterns between scenes, and REST lengthens stillness. EVENT RATE remains the physical clock, and HOLD suppresses scored events.

Presets and SURF

Eighteen factory scenes establish distinct process regions: Alpine Frost Crack, Ice Segregation Gneiss, Permafrost Heave, Basal Glacier Stick-Slip, Pressure Ridge, Calving Front, Iceberg Water Impact, Avalanche Release, Snowpack Creep, Hail on Metal, Sleet on Glass, Meltwater Under Ice, Ice Under Foot, Singing Lake Ice, Tidal Ocean-Moon Rift, Methane-Ice Dune Creep, Subsurface Brine Upwelling, and Quasicrystal Plate Bloom. The final four select four dedicated planetary engines with sparse event-excited modal matter: tidal shell rupture, cohesive hydrocarbon-frost transport, reactive brine seal cycles, and aperiodic-lattice propagation. They are unfamiliar material ecologies and planetary timescales—not conventional science-fiction weapon effects.

The SURF page stores complete presets as editable cells. Automatable Surface X/Surface Y coordinates blend continuous event, body, motion, environment, and score parameters; discrete regimes and materials select the nearest cell. VOICES stays an integer readout while surplus frozen-water parcels fade continuously in both synthesis and the field drawing. Curve, focus, and up-to-two-second glide settings are saved with project state; POP opens the synchronized surface in an attached utility panel.

Order and Routing

The output bus remains 64 channels wide. ORDER activates the corresponding ACN channels and clears the rest.
